MPROVEMENT IN PRINTING-PRESSES Specification forming part of LettersPatent N o. 9,993, dated September (i, 1853.

T0 @ZZ whom, t may concern.:

Be it known that I, CHARLES MONTAGUE, of Pittseld, in the county ofBerkshire and State of Massachusetts, have invented anew and ImprovedPrinting-Press for Printing on a Continuous Sheet; and I do herebydeclare that the following` is a full and exact description thereof,reference being had to the accompanying drawings, making part of this4specitication- Figure l being a longitudinal vertical section of thepress, and Fig. 2 a section of adetached part thereof.

Like letters designate corresponding parts in both figures.

" vI make use of a horizontal bed B, to which` -a crank Gandconnecting-rod H orother suitable means.

The ink-'rollers o o o, dac., for distributing,` .the ink to the form n:at each stroke of the bed are supplied with ink from a large roller D,situated below the bed, by means of traveling rollers. yr fr', turningin the vibratory ends of conducting-arms q q, which `are ar-Y rangedland operated in the following `manner, viz: They are attached' tovibratory rollers p j), around which pass cordst t, as shown in Fig. l,whose other ends are attached to a springs or other elastic holdersecured to the drivingdever Cin such a manner that the left cord t willbe straightened and turn its roller p, so as to carry thelett arm androller qand 9' up to the lett ink-rollers when theI driving-lever Cpasses to the'right, as shown -in Fig. l, While at the saine time theright cord is loosened, so as to let down the right conducting-roller tothe large roller D, and vice versa. The use of the spring s is toobviate the difficulty of adjusting a positive action of the lever C onsaid conducting-rollers with sufficient exactness and to produce anelastic pressure of the said conducting-rollers on thei'r'respectiveink-rollers o o o.

The' continuous sheet a is,a first wound around a roller g at one end ofthe press. .It is then vpassed down under the pressure-cylinder A andthence up around awinding-cylinder F. at the other end of the press,ready to be wound upon a roller f, which rests on said cylinder E,turning and moving up and down inn guides j, so that it may adjustitself to the dierent sizes it assumes as the sheet is received thereon.A cog-Wheel Z) on one end of the pressure-cylinder communicates motionby the rack 7c from the bed to said cylinder and through cog-Wheels c cc c precisely equal motion to two rollers (Z (l, one on each side of thecylinder. The winding-cylinder E is geared by cog-wheels c c tothe.lefthand roller d in such a manner that its periphery will move justtwice asfast as the peripheries of the cylinder A and rollers cl d.Small rollers e e e are situated, respectively, below the cylinder E androllers el d, so near as to hold the sheet a, which passes over them, incontact with said cylinders and rollers, as represented in Fig. 1.

The cylinder E is provided with a coupling device, by which it is causedto revolve only in one direction-viz., that indicated by the ar'rowinFig. l-and reinainsstationary during the opposite movement of the restof the press. Any convenient and suitable device may be employed forthat purpose. I usually employ that represented in the drawings and mostclearly shown in Fig. 2, which is a central section of that end of thecylinder E to which' the device is attached. The -cog-wheel c( isprovided with a short tube or elongated hub extending over the shaft Zinto. a recess in the end of the cylinder, which tube terminates inI adisk m, Whose face is formed into a series fof radial notches withperpendicular sides in one direction and oblique sides in the otherdirection, which titinto corresponding notches in reverse at the bottomof the recess of the cylinder. Said.' disk is pressed intothe recess byal spring fn, whichl thuscouples the cogavheel c to the cylinder E whenrevolving in one direction, (indicated by the arrow in Fig. 1,) butallows it to slip without turning said cylinderwhen moving in the otherdirection.

Between the Winding-cylinder E and the adjacent roller d is situated afeed-roller h, which-rests upon the sheetor web of paper turning andmoving up and down in slots or staples Said feed-roller is of a suitableweight to enable the friction of the rollers fl d and ce and of thepressure-cylinder and form, when' in motion, with the papento raise saidroller by straightening the sheet beneath it, but so that it will sinkto thev bottom of its slotted bearings and' draw down the paper with itas soon as the rollers d d and pressre-cylindercease to turn and theform 'leaves the paper at the end of each stroke-of the bed.

rlhe operation of the press is in the following manner, to wit: Supposethe. press to be in the position in which the bed B. is just becylinder,but just as much more by straightening the slack under the roller h,thereby raising said roller and the paper beneathit to the positionindicated by the dotted lines, Fig. l. As soon as the bed comes to theend of its stroke and clears the pressure-cylinderA said roller h fallsback to the bottom of its slots, and thereby brings forward enough ofthe paperfrom the roller g for an impression. Then when the oppositestroke ot' the bed is madeihe Winding-Cylinder E remain Stationary andprevents the-sheet from unwinding again; but that part-of the sheetunder the pressure-cylindenis carried back as much as the periphery ofthe pressure-cylinder moves or sufficient for one impression, therebyagain bringing up the roller h to the position shown by the dottedlines. As soon as this stroke is finished the said'roller again falls tothe bottom of' its slotted bearings and brings' forward again thatportion of the sheet which was carried back and impressed in the-laststroke, and the press thus assumes the same position, as shown in thedrawings, ready vfor another forward stroke. By this arrangement anim.-pression is taken at each stroke of the bed upon a continuous sheet.When one side of the. said sheet has thus been printed, the rollerf isput inthe place of the roller g and the other side ofthe sheet printed,during which'operation a device may be employed for cutting off eachcopy as fast as printed, instead of winding the sheet again upon aroller.

.Having thus fully described my improved printing-press for printing ona continuous sheet, what I claim4 therein as new, and desire to secureby Letters Patent, is

l. The combination of the intermittently- Winding cylinder E'andfeed-roller h or their equivalents with the reciprocatingpressurecylinder A, bed B, and rollers d d and e e e, arranged andoperating in such a manner'as to successively make an' impression on thecontinuous sheet at each movement of the bed, substantially as hereinset forth.

2. In combination with a double set ofvinking-rollers, the arrangementofthe arms q q' proved printing-'press signed by me this 23d day of March,1853.
